二甲醚的制备与应用前景

Production and application prospect of dimethyl ether

综述了二甲醚的性质、制备方法、应用前景,比较了二甲醚制备方法的优缺点,其中,一步法生产二甲醚具有较高的经济价值。二甲醚作为一种重要的清洁能源和环境友好产品,其在车用燃料、民用燃料、化工原料方面的应用研究越来越受到重视,特别是作为燃料电池的燃料有着广阔的发展前景。

The properties, production methods and application prospect of dimethyl ether（DME） are reviewed. In comparison of the advantages and disadvantages of different production methods, it is concluded that the one-step synthesis of DME from syngas is the best route. Research on the application of DME in the area of vehicle fuel, domestic fuel, chemical material especially in fuel cells draws more and more attention because DME is one of the most important clean fuels and environmentally benign product.
